you might want to split your database, this link should be helpful: http://allenbrowne.com/ser-01.html
for hiding the ribbons, insert this code behind the first form that will be loaded:
Code:
Private Sub Form_Load()
DoCmd.ShowToolbar "Ribbon", acToolbarNo
End Sub
Also, another trick you might find useful is hiding the navigation bar:
File > Options > Current Database > Untick "Display Navigation Pane"
To temporarily show the ribbons and navigation pane, hold shift when opening the DB (this disables the autoexec)
